NEW HAMPSHIRE TENTHREDINID^. 



BY ALEX. D. MACGILLIVRAY, ITHACA, N.Y. 



The new species described below were contained in a collection of 

 saw-flies recently received from Mrs. Annie Trumbull Slosson, and were 

 collected on Mount Washington and at Franconia, New Hampshire. The 

 collection was of interest on account of the number of species it contained 

 which are evidently related to a boreal fauna. 



Macrophya mixta, n. sp. — $ Black, with the following parts white: 

 two spots on the clypeus, the labrum, a spot on each mandible, two spots 

 on the occiput pseudocaudad of the ocelli, a narrow line on collar and 

 tegulse, the anterior coxs at apex and a narrow line at side, the middle and 

 posterior coxa? at apex, the trochanters, the distal halves of the anterior 

 femora, the anterior tibiae beneath, the knees of the middle legs, the middle 

 tibiae beneath, the posterior tibise with a band at middle, all the tarsi except 

 the base of the first segment and the apices of the others, a large spot on the 

 posterior coxse, two spots on the caudal margin of the basal plates, and a 

 narrow margin on basal plates at side; costa and stigma black; lanceolate 

 cell closed ; clypeus emarginate ; third segment of the antennae twice the 

 length of the fourth ; head coarsely punctured. Length, 8 mm. 



Habitat. — Mount Washington and Franconia, New Hampshire. 



This species is related to flavicoxce, Nort., but readily separated by 

 having the posterior femora wholly black. 



Macrophya nidonea, n. sp. — ^ Black, with the following parts white : 

 the clypeus, labrum, a spot on each mandible, the eighth and ninth seg- 

 ments of the antennae, the collar, the scutellum, a narrow transverse band 

 on the metathorax, the apices of all the coxte, the trochanters, a spot on each 

 of the posterior coxse, the basal third of the posterior femora, the posterior 

 tarsi beyond the middle of the basal segment (their apices are fuscous), 

 abdominal segments two to five above and below (the following segments 

 are blackish-piceous), and a small dot near the apices of posterior tibiae 

 above ; first segment of the antennae but little longer than second, third 

 and fourth subequal ; costa pale, stigma black ; lanceolate cell closed. 

 Length, 8 mm. 



Habitat. — Franconia, New Hampshire. 



Near tj-isyllabus, Nort., but readily recognized by the almost wholly 

 black posterior femora and tibiae.
